Scenario 3 Kanye has been noticing that his backup dancers seem very sluggish. He wants to set up an experiment
to see how he could help them get their freshness back. He has a total of 24 backup dancers on his tour,
so he divides them into three groups of eight. He decides to make no changes to Group A, and allow
them to continue their regular routine of dancing all night, and going out after the show with irregular
sleeping patterns. Group B, however, is asked not to go out after the show and return to their busses to
relax, getting at least eight hours of sleep a night. Group C is also asked not to go out after the show
and get at least eight hours of sleep, but are also asked to exercise at least 30 minutes when they wake
up. After a week of their new schedules, Kanye decides to watch recording of the next three shows in
his bus. He notices Group A is as sluggish as ever. Group B and Group Clook very fresh though and
complete the show with as much energy as they started.
